As a result, their music was infused with a quirky sense of humor and an endearing awkwardness that made songs from their debut Weezer (aka the blue album) like "Undone (The Sweater Song)," "Buddy Holly," and "Say It Ain't So" into big modern rock hits during the mid-'90s. All the singles were helped immeasurably by clever videos, which may have made the songs into hits, but they also made many critics believe that the band was a one-hit wonder. Perversely, Cuomo began to feel the same way, and decided that the band would not rely on any visual gimmicks for its second album, 1996's Pinkerton. Simultaneously, Cuomo took control of the band, making it into a vehicle for his songwriting. While the album didn't sell as well as their 1994 eponymous debut, it did earn stronger reviews than its predecessor and paved the way for Weezer's long career.

Cuomo's assumption of Weezer's leadership wasn't entirely a surprise, since he had been the band's primary songwriter since its inception in 1993. Raised in Massachusetts, Cuomo moved to Los Angeles to attend college in the late '80s. During high school, he had played with a number of metal bands, but his interests broadened to include alternative and post-punk music upon his move out West. By 1993, he had fused such interests together and formed Weezer with bassist Matt Sharp and drummer Patrick Wilson. Over the course of the next year, the group played in the competitive Los Angeles club scene, eventually landing a deal with DGC during the post-Nirvana alternative signing boom. Three days before Weezer began recording a debut album with producer Ric Ocasek, they added guitarist Brian Bell to the mix. Upon completing the record, Weezer went on hiatus temporarily; Cuomo was studying at Harvard when their eponymous debut record came out. With the support of DGC and a striking, Spike Jonze-directed video, "Undone (The Sweater Song)" became a modern rock hit in the fall of 1994, but what made Weezer a crossover hit was "Buddy Holly." Jonze created an innovative video that spliced the group into old footage from the sitcom Happy Days and the single quickly became a hit, making the album a multi-platinum success as well.

By the time the album's final single, "Say It Ain't So," was released in the summer of 1995, the group had gone on hiatus once again, with Cuomo returning to Harvard. During the time off, Sharp and Wilson formed the new wave revival band the Rentals, who had a hit later that year with "Friends of P." During the hiatus, Cuomo became a recluse, disappearing at Harvard and suffering writer's block. When Weezer reconvened in the spring of 1996 to record their second album, he had written a loose concept album that featured far more introspective material than their debut. Ironically, the band sounded tighter on the resulting album, Pinkerton. Released in the fall to generally strong reviews, the album failed to become a hit, partially because Cuomo did not want the band to record another series of clever videos. Grudgingly, the remainder of the bandmembers contented themselves to be a supporting group for Cuomo, largely because each member had his own solo project scheduled for release within the next year. DGC, however, had the band make one last chance at a hit with "The Good Life," but by the time the single was released, MTV and modern rock radio had withdrawn their support not only of Weezer, but their style of guitar-driven punk-pop in general.

Shortly after the tour in support of Pinkerton was completed in 1997, it appeared as though Weezer had fallen off the face of the planet. Stung by the public's initial reaction to their sophomore effort (Rolling Stone even named Pinkerton the Worst Album of 1996), the band took time off to regroup and plan its next move. Unhappy with the sluggish rate of the reassessment period, Sharp left the group to concentrate more fully on the Rentals, fueling rumors that Weezer had broken up. But a funny thing happened during Weezer's self-imposed exile -- while their copycat offspring were falling by the wayside (Nerf Herder, Nada Surf), a whole new generation of emocore enthusiasts discovered Weezer's diamond-in-the-rough sophomore effort for the first time, and their audience grew despite not having a new album in the stores.

Once Weezer's members wrapped up work on their side projects (Bell: Space Twins; Wilson: the Special Goodness), the band recruited former Juliana Hatfield bassist Mikey Welsh to take the place of Sharp and began working on new material. Before they could enter the recording studio to record their third release, however, Weezer tested the waters by landing a spot on the 2000 edition of the Warped Tour, where they were consistently the day's highlight. Hooking up again with the producer of their 1994 debut, Ric Ocasek, Weezer recorded what would be known as "The Green Album" (an informal title given by fans, since it was actually their second self-titled release). The album was an immediate hit, debuting at number four in May 2001 and camping out in the upper reaches of the charts for much of the spring/summer, during which such songs like "Hash Pipe" and "Island in the Sun" became radio and MTV staples, reestablishing Weezer as one of alt-rock's top dogs. During their tour that summer, Welsh fell ill and was replaced by Scott Shriner, also of the band Broken. (Welsh died in Chicago in October 2011 at the age of 40.) That fall and winter, the group busied itself with touring alongside bands like Tenacious D and recording its next album, Maladroit, which arrived a year after The Green Album's release.

Just before Maladroit's release, former bassist Matt Sharp sued Weezer, seeking compensation and songwriting credit for songs such as "Undone (The Sweater Song)," "El Scorcho," and "The Good Life." The band eventually reconciled with Sharp, though he didn't rejoin, and Weezer continued on with the lineup of Cuomo, Bell, Wilson, and Shriner. The limited-edition live EP Lion and the Witch appeared in May 2002, and Maladroit's "Keep Fishin'" was released as a single. Most of 2003 was spent on side projects; Cuomo did some hired-gun songwriting, Bell's band the Space Twins put out End of Imagining, and Wilson's Special Goodness project issued Land Air Sea. Weezer returned to the studio in 2004, working with Rick Rubin on their fifth full-length album. Make Believe appeared in May 2005, prepped by the single "Beverly Hills," and eventually went platinum in multiple countries. Weezer (Red Album) followed in 2008 and featured a more collaborative approach, with several bandmembers contributing songwriting ideas and lead vocals to the tracks. One year later, the band returned with Raditude. Greeted with mixed reviews, Raditude marked Weezer's last album for Universal. They jumped to the indies in 2010, releasing Hurley on Epitaph. The new album was quickly followed by two archival releases: an expanded deluxe edition of Pinkerton and the outtakes collection Death to False Metal.
